PUMP.

Application filed J'uly 29, 1826.

This invention relates to pumps and more particularly to an operating mechanism therefor facilitating the operation of the ordinary hand pump.

An important object of the invention is to provide a structure including weights arranged as pendulums, the swing of which tends to operate the pump through suitable connections.

A further object of the invention is to provide a device of this character which may be very cheaply and readily produced and installed, which will be durable and eiiicient in service and a general improvement in the art.

These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a prefered embodiment of my invention and wherein Figure 1 is a vertical sectional view through the pumping apparatus constructed in accordance with my invention;

Figure 2 is a section on'the line 2 2 of Figure 1.

In .accordance with my invention, I arrange adjacent the pump 10, the rod 11 of which is to be operated, a pair of spaced standards 12, the upper ends of which are connected by a cross bar 13. Beneath the cross bar a rock shaft 14 is disposed to which are rigidly secured a pair of normally depending arms 15, the lower ends of which have secured thereto relativelyf heavy weights 16. The shaft has projecting from the center thereof a substantially horizontal arm 17. Secured to the center of the cross bar 13 is an inverted itl-shaped yoke 18 between the arms of which a lever 19 is pivoted at a point intermediate its ends. One end of this lever is connected with the underlying free end of the arm 17 by a link 20. The opposite end of the lever is preferably connected by a link 21 with one end of a treadle 22, the opposite end of which is pivotally connected, as at 23, to a suitable support 24. rIhe pump rod 11 is preferably connected. to the lever 19. In operation, depression of the treadle 22 will cause the pump rod to be elevated and will likewise cause elevation of the free end of the arm 17, rocking the shaft 14 and thereby swinging the weights 16 to one side of the Serial No. 125.82%.

position which they normally occupy. As the weight upon the treadle is released, the weights will naturally tend to return to their normal position and because of their weight to pass this normal position. starting the pendulistic action which may be increased by an intermittent pressure upon the treadle 22. It will be quite obvious that swinging of the pendulum will Inaterially reduce the amount of labor necessary to cause an actuation of the pump rod 11 after operation of the pump has once been started.

It will furthermore be obvious that certain changes of the structure may be resorted to without in any manner departing from the spirit of the invention and I accordingly do not limit myself to the specific structure hereinbefore set forth except as hereinafter claimed.

I claim:-

l. In a pump operating mechanism and in combination with a pump rod, a horizontal rod shaft, an arm depending therefrom and having a weight at its free end, a second arm projecting outwardly from the shaft, a lever pivoted intermediate its ends and link-connected with the free end of the lever of the last named arm and with which the pump rod is adapted to be operatively connected and a treadle hinged at one end and having the opposite end thereof link-connected with the opposite end of the lever. l

2. In a pump operating mechanism and in combination with a pump rod, a horizontal rock shaft, an arm depending therefrom and having a weight at its free end, a second arm projecting outwardly from the shaft, a lever pivoted intermediate its ends and link-connected with the free end of the lever of the last named arm and with which the pum rod is adapted to be operatively connecte spaced vertical standards in which the ends of the rock shaft are mounted and a cross bar connecting the standards above the rock shaft and providing a mounting for the pivot of the lever.

3. In a pump operating mechanism and in combination with a pump rod, a horizontal rock shaft, an arm depending therefrom and having a weight at its free end, a second arm projecting outwardly from the iet shaft, a level` pivoted intermediate its ends standards above the rock shaft and providand link-connected with the free end of the ing a, mounting for the pvot of the lever lever of the last named arm and with and a pivot-ed treadle operatively connected i0 which the pump rod is adapted to be 0pwith the opposite end of the lever.

eratively connected, spaced vertical stand- In testimony whereof hereunto affix my ards in which the ends o the rock shaft signature.

are mounted, a cross bar connecting the JOHN S. RAGAR.
